PILE FABRIC AND'MANUFACTURE OF SAME.

SPECIFICATION forming'part of Letters Patent No. 760,986, dated May 24, 1904.

Application filed February 12, 1904. Serial K 193348- (No model.)

To all w/wm it may concern:

Be it known that I, HARRY HARnwIcK,.a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented Improve- 5 ments in Pile Fabrics and Manufacture of the Same. of which the following is a specification.

My invention relates to that class of pile fabrics having uncut loops; and the object of my invention is to produce pattern eifects in such fabric without of necessity employing yarns of different color for this purpose, al-

7 though the yarns may be differentlycolored, if desired. This object I attain by making some of the pile-loops longer than others in I 5 the direction of the warp-line of the fabric,

these longer loops having a different effect upon the eye from that produced by the shorter loops.

In the accompanying drawings, Figure 1 represents a face View of a piece of fabric made in accordance with my invention. Fig.

2 represents an enlarged sectional View of the same, taken partly through a portion of fabric having short loops and partly through a por- 2 5 tion of fabric having long loops; and Fig. 3 is a view, on a somewhat larger scale than Fig. 2, illustrating the method of weaving the fabric.

In carrying out my invention I may employ any desired form of backing fabric, into which the pile-forming warp-threads are tied, and I can use any ordinary form of pile-loom for weaving the fabric, since no change is needed in the mechanism for inserting and drawing 3 5 the pile-wiresor in any other part of the loom, the novel fabric produced being due to a slightly different shedding of the warpthreads from that adapted in weaving an ordinary pile fabric having all of its pile-loops 4o alike.

In the drawings I have shown a fabric having a backing composed of weft-threads 1 and 2, stuffer Warp-threads 3, and binding warpthreads 4 and 5, the pile-loops 6 and 7 being tied into this backing fabric by the weftthreads 1 on the upper surface of the backing.

The short pile-loops 6 are tied to the backing by each of said upper weft-threads 1, as in the usual method of weaving pile fabric; but the longer loops 7 are only bound to the backing fabric at correspondingly-longer intervals. Thus, as shown in Figs. 2 and 3, they are bound down only by every other one of the weft-threads 1. While a row of long loops is therefore bound into the backing fabric wherever a row of shorter loops is thus bound, there are rows of short loops separately tied into the backing fabric between such common tying-points. Hence wherever in the fabric there are short and long pile-loops lying in the same transverse plane the long pile-loops will extend longitudinally over a distance equal to two or more rows of short pile-loops.

In weaving the fabric the short loops 6 are formed over each pile wire 8, as shown in Fig. 3; but the longer pile-loops 7 are carried over two or more successive pile-wires. Thus, as shown in Fig. 3, each long pile-loop extends over two adjoining pile-wires 8. It will be observed that all of the pile-loops are of the same height. Hence my invention is distinct from a pile fabric in which some of the pileloops are higher than others, the terms long and longer as used by me indicating greater length in the direction of the pile-warp and not greater height of pile-loop.

The long and short loops of my improved fabric have a distinctly different effect upon the eye. Hence I can produce patterns in the fabric even without the use of different colors, although a still greater difference in appearance may be obtained, if desired, by making the long loops of a different colored yarn or yarns from the yarn or yarns employed for the short loops.

Having thus described my invention, I claim and desire to secure by Letters Patent 1. A pile fabric having uncut loops, some of which are longer than others in the direction of the warp-line of the fabric, substantially as specified. L

2. A pile fabric having pile-loops, some of which are tied into the backing fabric at less frequent intervals than the others, substantially as specified.

3. A pile fabric havinglong and short pileloops, the long pile-loops being tied into the backing fabric in line with the tying-points of the short pile-loops, and one or more rows of such short pile-loops being separately tied into the backing fabric between such common tying-points, substantially as specified.

4. A pile fabric having long and short pile-V loops in the same tranverse plane, the long pile-loops extending longitudinally over a distance equal to two or more rows of short pileloops, substantially as specified.

5. The mode herein described of producing a pile fabric having long and short pile-loops,

said mode consisting in forming the long loops over a greater number of wires than the short loops, substantially as specified.

6. The mode herein described of producing a pile fabric with long and short pile-loops, said mode consisting in forming the short loops over successive single wires and the long loops over groups of successive single Wires, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

HARRY HARDWIOK.
